Republican senator tom coburn triggers of washington watchdog report and abc's jonathan karl has this report. Reporter: The zombie apocalypse. This isn't some really bad b-movie. It's an actual scene from the 2012 counterterrorism summit attended by law enforcement officials around the country. Summit tickets, $1,000 a pop, paid for with your tax dollars. The zombies look scary, but organizers say the skit was solely to add levity to an otherwise serious meeting on protecting the homeland. Senator tom coburn says it's an exhibit in $7 billion in questionable homeland security spending every year. Wasteful. Reporter: In a new report, coburn sites example after example, including nearly $0,000 for an underwater robot in columbus, ohio. 69,000 hovercraft for indianapolis. And this. A sleepy town of keene, new hampshire, siting the need to secure its annual pumpkin festival, was awarded a grant to buy a bearcat armored vehicle. Price tag? Nearly a quarter of a million dollars. Department of homeland security told us its grants, quote, make our communities safer places to live. Coburn says there's just too much waste. The examples you site here are the tip of the iceberg? Sure. All over the government. Everywhere you look. Reporter: Is what? Is waste. Incompetence and stupidity. Reporter: But again, could you ever be too prepared for the zombie apocalypse?
